These guns were produced from 1961-1974 and have tremendous value for any serious Smith & Wesson collector.
The S&W Model 53 introduced the .22 Remington Jet cartridge and is only one of two guns ever produced in the .22 Remington Jet caliber (The other being the Thompson Contender single shot).
They also usually came with an additional 22 Magnum cylinder too.
These guns have great appeal to varmint hunters and for field use. (Until you need to buy some factory ammo)
The .22 Jet cartridge “set-back” problems have been well documented but overrated.
Keeping the chambers clean with an occasional spray of “Gunscrubber” or naptha makes the gun as reliable as most revolvers.
The cartridge is a delight to reload, and .357 Magnum brass can be utilized to produce new cases.
